The drinking probably isn't the only thing that followed you out of the Corps. I can read it in your writing. How are you coping other than the drinking? Sorry about your buddy, I've lost many in this manner as well. Address the drinking but make sure you adress the underlying causes as well. I think you'll find many who thought they started drinking due to work pressures, and later found there were deeper issues at work. Never be afraid to admit you need help. PTSD is very real, and must be adressed in a timely manner. Welcome, and know you're in a safe place here. That may not mean a lot right now but it will. Any time you need to talk, I'm around, and there are many others here as well. I'm sure you'll meet them.
